To all whom it may concern:

Be it known that we, WILLIAM H. SMALLEY and I'IARVEY RAY SMALLEY, citizens of the United States, residing at. Corning, in the county of Clay, Stateof Arkansas, have in vented certain new and useful Improvements in Telegraph-Poles; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates totelegraph poles.

The primary object of our invention is to provide, in a telegraph pole, a ladder construction of such character that only licensed personsmay ascend the pole. At the present time, it is customary to employ wooden poles for stringing telegraph wires but these poles possess disadvantages among which are liability to rotting at the base and in addition to this, they may he climbed by unauthorized persons. In carrying out our invention, we form the pole proper of hollow cylindrical construction and arrange within the pole, a ladder mechanism which may be operated by the proper persons so as to project rungs through the wall of the pole into position for use, the rungs being normally supported within the poleso as to afford no foothold whereby unauthorized persons are prevented from climbing the pole.

Another feature of our invention resides in the provision at the upper end of the pole of a wooden head to which the cross trees are secured together with novel means for securing this head to the pole.

In theaccompanying drawings, Figure 1 is a front elevation of the pole constructed in accordance with our invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical sectional view taken in a plane from side to side and showing the movable stile and the rungs pivoted thereto in front elevation, the said rungs being shown in retracted position. Fig. 1 is a similar view but showing the rungs in projected position. Fig. 5 is a vertical sectional view taken in a plane at right angles to the plane ofFig. 4c. Fig. 6 is a horizontal sectional view on the line 66 of Fig. Fig. 7 is a horizontal section on the line 7-7 of Fig. 3. Fig. 8 is a horizontal section on the line 8-8 of Fig. l. Fig. 9 is a detail perspective view of the rung shown in Fig. 7 of the drawings. Fig. 10 is a top.

plan view of a slightly modified form of pole. Fig. 11 is a detail vertical sectional view showing another form of stationary rung.

As shown in the drawings, the pole embodying our invention comprises a tubular upright 10 which is preferably of greater diameter at its lower. end than atits upper end and is provided at its lower end with anchor braces 11 of which there are several which are to be embedded in the foundation for the pole.

Secured in vertical position upon the inner side of the wall of the upright at diametrically opposite points are stiles 12 there being two such stiles and each being of channel formation as is clearly illustrated in the horizontal sectional views of the drawings. Adjacent their lower ends, the stiles are con nected by means of a cross piece 1& and this cross piece is formed intermediate its ends with a slot 1.5, the upper endsof the stiles being connected by a similar piece .10 formed also intermediate its ends with a slot 17. The side stiles 12 of the ladder frame just described are formed at intervals throughout their extent with openings 18 and similar openings 19 are formed at corresponding points in the wall of the tubular upright 10. A mid-stile 20 is slidably engaged at its upper and lower ends through the slots 15 and 17 respectively and pivoted to this midstile, at their inner ends, are rungs 21 said rungs projecting alternately in opposite directions from the said mid-stile and pr0- jecting at their outer ends at all times through the openings 18 and in position to be projected through the openings 19. It will be understood of course that when the mid-stile 20 is in one position, the rungs 21 will project tl'irough the openings 18 and 19 in a horizontal direction and in position to afford footholds to a person climbing the pole, but that when the stile is moved verti' cally upwardlyfrom such position, the rungs will be retracted or in other words drawn into position within the upright 10. In order that the stile may be so moved and may be held raised or lowered, we have provided a mechanism which will now be specifically described.

At its lower portion, one edge of the stile .20 is of rack formation as indicated by the engagement therewith of a crank handle 26 by means of which the shaft may be rotated. This squared end 25 of the shaft 24 projects directly toward an opening 27 formed in the wall of the upright 10, it being understood of course that the socket end of the crank handle 26 is to be inserted through this opening and engaged over the squared end 25 of the shaft. By rotating the shaft and the pinion 23 carried thereby, it will be understood that the mid-stile 20 will be raised or lowered according to the direction of rotation of the gear, and that the rungs will be extended or retracted in the manner heretofore described. The other edge of the midstile 20 is formed with a notch 28 and a notch 29, the notch 28 being positioned directly opposite the upper end of the rack portion 22 of the mid-stile and the lower notch 29 being positioned below the notch 28, and mounted for rocking movement in suitable bearings upon the cross piece 14 is a shaft 30 which has fixed to it a pawl or detent 31, the shaft being squared at one end as at 32 in the same manner as the shaft 24 so that the crank handle 26 may be engaged therewith and the shaft be rocked to move the free end of its detent 31 into engagement in either of the notches 28 and 29. A stud 33 projects from the detent 31 and engaged with the stud and bearing against the adjacent side stile 12 is a spring 34 which acts to normally hold the free end of the detent 31 in engagement with the notched edge of the mid-stile 20 so that the engagement of the detent in the notches will be automatic, it being disengageable by manipulating the crank handle 26.

In order to'close the openings in the upright through which the crank handle 26 is to be inserted, there is hinged upon the said upright a door 34 and we provide at the outer edge of this door a hasp 35 which is engageable with a staple 36, when the door is closed, there beingalso provided an ordinary hasp lock 37 which may be engaged with the staple so as to prevent opening of the door except by parties provided with the proper key.

I11 addition to the rungs 21 heretofore described, we provide, adjacent the upper end of the pole, stationary rungs which are indi cated by the numeral 38 and which have their inner end portions threaded as at 39 and screwed through threaded openings 40, formed in the wall of the upright and the stiles 12 of the ladder construction.

In lieu of the rungs 38 there may be provided rungs 41 which are each formed with a notch 42. Each of these rungs 41 is inserted through a key-hole shaped opening 43 formed in the wall of the upright and into an opening in the stiles l2, and after such insertion, the rungs are rotated so as to bring their notches 42 in engagement with the edge of the opening in the wall of the upright, it being understood that the rungs are held, by reason of such engagement, against accidental displacement.

The upper end of the upright 10 is open as is clearly shown in the drawings and fitted into the said upper end of the upright is a wooden head 45 having secured to it at diametrically opposite points rungs 46 which rest against the said upper end of the upright. This head 45 also has secured to it one or more of the usual cross arms 47 upon which the insulators are mounted.

One advantage accruing from employing head of this type which is merely set into the upper end of the tubular upright lies in the fact that the head may be turned so as to position the cross arms at any angle de sired, they being of course always extended in a horizontal plane.

In the form of our invention shown in Fig. 10 of the drawings, the upper end of the upright 10 is not provided with the removable head 45 but with a cap 45, and encircling the upper end of the upright is a collar comprised of two sections 48 which are hinged together as at 49 and are formed at their other end with ears 50 throu h which a clamping bolt 51 is passed, the said bolt being adjustable to tightly clamp the collar sections around the upper edge of the upright. Formed integral with each of the sections or secured thereto in any suitable manner is an arm 52 and these arms carry insulators as in the case of the cross arms 47.
